SF6 - sulfur hexa floride has six sulfur - floride single bonds. Sulfur is at the center and 6 florine atoms are equally distributed in space ALL neighboring bonds being perpendicular to one another.
It is a octahedral structure. There are 4 planar florine and 1 sulfur : 5 total in one plane.
there are 5 isomers for phenyl methanol C7 H8 O: C6 H4 CH3 OH
1. 2- methyl phenol
In the hexagonal benzene ring, you have C-H at 4 vertices. Then at the 5th one you have C-CH3 and at the sixth OH. CH3 and OH groups are attached to Carbons which are adjacent to each other in the ring.
2. 3-methyl phenol
the CH3 and OH groups are attached to carbons in the ring, that are separated by 1 carbon in the middle.
3. 4- methyl phenol
the CH3 and OH groups are attached to carbons opposite to each other in the benzene ring.
4. methoxy benezene
group OCH3 is attached to one carbon in the benzene ring. O bonds with Carbon in the ring.
5. phenyl methanol
The group CH2-OH is attached to one carbon in the benzene. C bonds with carbon in the ring.
is it for n = 3 or l = 3 ?
if it is n = 3 , principal quantum number , then there are s, p and d orbitals in the shell. 1 s , 3 p and 5 d orbitals.
Is that l = azimuthal quantum number ?
l = 0 means the orbital or sub shell s
l = 1 => p orbital
l = 2 => d orbital
l = 3 => f orbital
In a shell , with n as the principal quantum number, we have many orbitals or sub shells with the above azimuthal quantum number l.
there are (2 l + 1) number of orbitals of type l.
Hence there are 1 orbital of type s. 3 of type p. 5 of type d. 7 of type f. A one orbital contains a pair of electrons, the capacities of orbitals are: s = 2 electrons, 3 p orbitals have 6 electrons. 5 d orbitals contain 10 electrons in total. 7 f orbitals have 14 electrons.
